First end 16 is installed adjacent to a shoreline 18 and in a preferred embodiment, carries a shore attachment point 20 used to anchor the first section 12 to the shoreline 18. Shore attachment point 20 provides access to dock assembly 10 while maintaining its position as forces are applied to dock assembly 10 during use. It will be understood that various types of anchors or attachments may be used for this purpose as will be recognized in the art. For example, attachment point 20 may be include an attachment between first section 12 and posts or other permanent anchors that are fixed to the shoreline 18, or may be an anchor that. Second end 22 of first section 12 is designed to extend out onto the body of water, in the depicted embodiment, second end 22 has support legs 24 with wheels 26 that contact the bed 28 of the body of water. It may be possible to adapt the teachings herein to a floating dock with floatation devices, or dock sections 12 and 14 may be supported on posts set on the bed of the body of water. While various methods of support may be used to support a dock, as will be understood by one skilled in the art, the example that is depicted and described uses support legs 24 with wheels as this facilitates the installation and removal of sections 12 and 14.

First section 12 has a bottom transport member 34 provided between first end 16 and second end 22. In a preferred embodiment bottom transport member 34 is a set of rollers. However, bottom transport member 34 may also be another transport device such as a skid or other low friction surface. Bottom transport member 34 is preferably positioned at a balance point of the first dock section 12. In the depicted example, this balance point occurs at a point approximately ⅗ of the length of the first dock section 12 toward the second end 22 to account for the additional weight of support legs 24.

Second end 22 has an attachment point 30 intended to attach to second dock section 14. Various attachments may be used as will be recognized. In one example, attachment point 30 uses brackets 31 shaped to receive first end 32 of second dock section 14. Brackets 31 may receive and hold second section 14, or may simply be used as a support and guide while additional attachments, such as bolls or clamps, are attached to secure first and section sections 12 and 14.

Cart 50 may also have a dock contact member 58 and guide members 64 at a second end 56, similar to cart transport member 54 and guide members 62. When used in combination with wheels 44 in the storage position, dock section 14 is guided at two points, which ensures that it will be properly aligned until wheels 44 extend past second end 22 of first dock section 12, at which point second end 38 of dock section 14 will need to be guided manually. Second end 56 also has a dock lifting device 60. Dock lifting mechanism 60 has an attachment device 66 shaped to attach to second dock section 14. As depicted, the attachment device 66 is a hook that is designed to engage trusses 36, but other attachments may also be used. Dock lifting mechanism 60 is used to lift second dock section 14. Dock lifting mechanism 60 may take various forms, such as a motor driven lifting device. In the depicted embodiment, dock lifting mechanism 60 is a hand crank mechanism 68. Cart 50 may also have a device 70 for moving the cart 50. The device 70 for moving the cart 50 may take various forms. For example, the device 70 may be a winch, such as a capstan winch, that can pull the cart as it carries second dock section 14. Device 70 may also be a motor that drives the cart transport member 54, pushing the cart as it carries second dock section 14. Cart 50 may also be manually operated and may not have a device 70.

Installation

The installation process of the depicted embodiment will now be described. Referring to FIG. 1, in order to install dock assembly 10, the first dock section 12 is placed into the water and attached to a shoreline 18. First dock section 12 will generally be manipulated manually using wheels 26. Once positioned, the height of support legs 24 is adjusted to level first section 12, with wheels 26 resting on the bed 28 of the body of water. Second dock section 14 is then moved onto first dock section 12 using bottom transport member 48, and guiding the movement with wheels 44, which preferably engage the sides of the first dock section 12 as shown in FIG. 17. Referring to FIG. 2, cart. 50 is then moved onto first dock section 12, and referring to FIG. 3, the cart 50 is positioned such that the cart transport member 54 rests on the first dock section 12 and the dock contact member 58 rests on the second dock section 14. Referring to FIG. 4, dock lifting mechanism 60 is attached to the second dock section 14 using attachment device 66. Referring to FIG. 5, dock lifting mechanism 60 is activated to apply a lifting force to the second dock section 14. This results in the cart 50 pivoting about the cart transport member 54 and the first end 32 of the second dock section 14 moves vertically relative to the first dock section 12, as shown in FIG. 15 and FIG. 16. This movement results in bottom transport member 48 becoming a balance point, such that the second dock section 14 is supported by the bottom transport member 48 and the cart transport member 54 while being guided by wheels 26 and guide members 62, while first end 32 of second dock section 14 is secured by guide members 64. Referring to FIG. 6, cart 50 is then used to move the second section 14 along the top surface 72 of the first dock section 12 to the point at which bottom transport member 48 reaches the second end 22 of first dock section 12. The respective positions of first section 12, second section 14, and cart 50 are further shown in FIG. 18. Referring to FIG. 7, at this point support leg 42 is preferably pivoted from the stored position adjacent to the dock section 14 to a support position extending downward from the dock section 14, as shown in FIG. 8. A guide and support device 43 may be positioned at second end 22 of first dock section 12. Preferably, guide and support device 43 includes rollers that support second dock section 14 in order to protect second end 22 of first dock section 12 as well as the underside of second dock section 14, if necessary. Guide and support device 43 also preferably has side flanges or guides that engage the sides of second dock section 14 to provide the function of wheels 44 when they no longer engage second dock section 14. Guide and support device 43 may be removed once wheels 44 engage the bed 28 of the body of water and can therefore support and help guide second dock section 14. Referring to FIG. 7, support leg 42 may be adjusted in length using hand crank 46 such that wheels 44 will be able to engage the bed 28 of the body of water. Referring to FIG. 9, second dock section 14 may then be further moved into the water until the wheels 44 reach the bed 28 of the body of water as shown in FIG. 10. Referring to FIG. 11, the second dock section 14 is then positioned such that the first end 32 of the second dock section 14 is adjacent to the second end 22 of the first dock section 12. Dock lifting mechanism 60 is then activated to lower second dock section 14. Referring to FIG. 12, second dock section 14 is lowered until the second section 14 can be attached to the first section 12 using attachment point 30. At this point the first end 32 of the second dock section 14 is level with the second end 22 of the first dock section 12. Referring to FIG. 13, the two dock sections 12 and 14 are then attached together and installation is complete. This process may them be repeated to install further dock sections to make dock assembly 10 longer. For any additional dock sections cart 50 would be removed from the second dock section 14 and attached to an additional dock section, which would be installed in the same manner as discussed for second dock section 14.

Removal

Referring to FIG. 13, an installed dock has at least two dock sections. As shown, dock assembly 10 has a first dock section 12 and a section dock section 14. It will be understood that dock assembly 10 may have more than two dock sections, and that the removal process as described would apply to dock assemblies 10 with more than two dock sections, in order to remove dock assembly 10 from the water, cart 50 is placed on dock assembly 10 such that it is adjacent to the first end 32 of the second dock section 14 and the second end 22 of the first dock section 12, and further such that such that the cart transport member 54 rests on the first dock section 12 and the dock contact member 58 rests on the second dock section 14. Referring to FIG. 12, dock lifting mechanism 60 of cart 50 is attached to the second dock section 14 using attachment device 66. Referring to FIG. 11, the attachment between first dock section 12 and second dock section 14 is then released at attachment point 30. Referring to FIG. 10, dock lifting mechanism 60 is then activated to lift the first end 32 of second dock section 14 by applying a lifting force to the first end 32. This results in the cart 50 pivoting about the cart transport member 54 and the first end 32 of the second dock section 14 moves vertically relative to the first dock section 12, as shown in FIG. 15 and FIG. 16. Second dock section 14 may then be moved towards the first end 16 of first dock section 12 using cart 50. Referring to FIG. 9, as second section 14 is moved, at some point the wheels 44 will no longer reach the bed 28 of the body of water. At this point second dock section 14 moves slidingly along first dock section 12 until bottom transport member 48 engages the top surface 72 of the first dock section 12 at the second end 22 of first dock section 12, as shown in FIG. 8. Preferably, guide and support device 43 is attached in order to guide second dock section 14 and protect both first and second dock sections 12 and 14. Once withdrawn sufficiently, the second dock section 14 is supported by the bottom transport member 48 and the cart transport member 54, and bottom transport member 48 becomes a balance point. The respective positions of first section 12, second section 14, and cart 50 are further shown in FIG. 18. Referring to FIG. 7, the support leg 42 can then be pivoted from the support position extending downward from the dock section 14 to the stored position adjacent to the dock section 14 as shown in FIG. 6. The length of support leg 42 may be reduced using hand crank 46 as shown in FIG. 7, however it is preferable to leave the length of support legs 42, as this will simplify re-installation in the next season. When in the stored position, wheels 44 preferably engage the sides of the first dock section 12 as shown in FIG. 17, and guide the movement of second dock section 14 along first dock section 12. Referring to FIG. 5, cart 50 is then used to move the second section 14 along the top surface 72 of the first dock section 12. Referring to FIG. 4, when the second dock section 14 has moved sufficiently far along first dock section 12 that the user no longer desires to use the cart, dock lifting mechanism 60 is activated to lower second dock section 14 to the surface 72 of first dock section 12. Referring to FIG. 3, dock lifting mechanism 60 is then removed from the second dock section by releasing attachment device 66. Referring to FIG. 2, the cart 50 can then be removed from the first dock section 12. Referring to FIG. 1, the second dock section 14 can then be moved off of first dock section 12. At this point, wheels 44 may be used to transport second dock section 14, as bottom transport members 48 are smaller and primarily for use in transporting dock section 14 across the decking of first dock section 12. In order to remove first dock section 12 from the water it is released from the shoreline 18 using attachment point 20 at first end 16. Support, legs 24 may be adjusted in length or pivoted to a stored position as with second dock section 14. First dock section 12 can then be removed from the water using wheels 26. Support legs 24 may or may not be folded to the transportation position. As can be seen, first dock section 12 has been manufactured to be the same as section dock section 14 for ease of manufacturing and to allow dock sections to be exchanged if necessary. However, it will be understood that certain features and elements, such as 34, may not be necessary for first dock section 12.
